2004-2014 Mercury 20” Optimax Lower Unit 75 90 115 HP 3 Cyl 2.07:1 1 YEAR WTY!

When we opened this up, we noticed that the gears look almost brand new. There are scuffs and scratches in the paint, but nothing that will affect performance and is very common in lower units. This does come with the trim tab and zinc anode. There is some wear around the paint and the edge of the skeg, but nothing that will affect performance. Please note that this does not come with the propeller or the propeller hardware. There is nothing stopping this lower unit from being a great replacement! Purchase with confidence!

Driveshaft measures approximately: 20-7/8"
Driveshaft spline count - 13
Propshaft spline count - 15
